Scratchboard is either a stiff paper or board that has been coated with a thin layer (the boards usually have a thicker layer than the paper) of white or colored clay. Ink or paint is applied over the top of the clay, either by the artist or the manufacturer. It was originally designed in the 1800's, as a quick and inexpensive alternative to other etching methods for illustrations needed in printing books, newspapers and etc.

  There are several types and qualities of scratchboard. What a particular artist uses depends on what the purpose of the drawing is (whether for school, fine or commercial applications) or personal preference. I use a heavy weight board that has been coated with white clay and black india ink. I feel it provides the best surface for the fine detailed scratchboard drawings I create.
 
   Scratchboard can be purchased coated with a variety of colors and textures as well as the traditional black ink. You can also purchase the boards coated with just the white clay. Then apply whatever medium you want, such as colored inks, watercolors, or acrylics. They can be applied in a variety of ways, such as the traditional brush or airbrush, depending on the textures and effects you are looking for.

   There are also a wide variety of tools available to use to remove the black ink or color from the clay. They range from the special scratch tools you can buy to dental tools that an artist can adapt for their purpose. I use a # 11 exacto blade. It allows me to create fine to thick lines. They are readily available and I can sharpen them using a sharpening stone.
